Problem following Chrome's Update today

Chrome updated itself today to version “33.0.1750.117 m”.  Now every time I open it, I get a message that points to Norton’s icon and says I must “Disable developer mode extensions”.  Chrome is my primary browser, but I won't use it without the Identity Protection.  Firefox uses the same version of Norton's extension, but doesn't have this problem.   

 

Is this happening to anyone else?
